FOD8012 High CMR, Bi-Directional, Logic Gate Optocoupler

General Description

The FOD8012 is a full duplex, bi-directional, high-speed logic gate Optocoupler, which supports isolated communications allowing digital signals to communicate between systems without conducting ground loops or hazardous voltages. It utilizes Fairchild’s proprietary coplanar packaging technology, Optoplanar®, and optimized IC design to achieve a minimum of 20kV/µs Common Mode Noise Rejection (CMR) rating.This high-speed logic gate optocoupler is highly integrated with 2 optically coupled channels arranged in bi-directional configuration, and housed in a compact 8-pin small outline package. Each optocoupler channel consists of a high-speed AlGaAs LED driven by a CMOS buffer IC coupled to a CMOS detector IC. The detector IC comprises of an integrated photodiode, a high-speed trans-impedance amplifier and a voltage comparator with an output driver. The CMOS technology coupled to the high efficiency of the LED achieves low power consumption as well as very high speed (60ns propagation delay, 15ns pulse width distortion).
